“Invalid Entry” Automatically returns to main menu


IVR Definition NOTES: 1. Once the button is pressed, it enters the voice prompt main menu. If the button is pressed again,

while it is already in the voice prompt menu, it jumps to “Direct IP Call” option and a dial tone is prompted

2. “*” shifts down to the next menu option “#” returns to the main menu “9” functions as the ENTER key in many cases to confirm an option

3. All entered digit sequences have known lengths a. 2 digits for menu option and 12 digits for IP address. b. For IP address, add 0 before the digits if the digits are less than 3 (example:

192.168.0.26 should be key in like 192168000026 – no period (.) is needed during input). c. Once all of the digits are keyed in, the IP address will be processed.

4. Key entry can not be deleted but the phone may prompt error once it is detected


PLACING A PHONE CALL PHONE OR EXTENSION NUMBERS 1. Dial the number directly and wait for 4 seconds (Default “No Key Entry Timeout”); or 2. Dial the number directly and press # (Use # as dial key” must be configured in web configuration). Examples: 1. Dial an extension directly on the same proxy, (e.g. 1008), and then press the # or wait for 4 seconds. 2. Dial an outside number (e.g. (626) 666-7890), first enter the prefix number (usually 1+ or international

code) followed by the phone number. Press # or wait for 4 seconds. Check with your VoIP service provider for further details on prefix numbers.

DIRECT IP CALLS Direct IP calling allows two parties with VoIP devices (e.g. HT496 and another VoIP Device), to talk to each other in an ad hoc fashion without a SIP proxy. Direct IP calls are possible if:

a) Both VoIP devices use a public IP address; or b) Both VoIP devices are on the same LAN using private IP addresses, or c) Both VoIP devices can be connected through a router using public or private IP addresses (with

necessary port forwarding or DMZ). To make a Direct IP Call, use either the handset or the speakerphone. Access the IVR using “***”, the button on the HT496or “47”. After dial tone, enter a 12-digit target IP address to place a call. Destination ports can be specified by using “*4” (encoding for “:”) followed by the port number. Examples:

a) If the target IP address is 192.168.0.160, enter the 12 digit IP address (e.g. 1921680160) after the voice prompt followed by the “#” key or wait for 4 seconds. The default destination port 5060 is used if no port is specified.

b) If the target IP address/port is 192.168.1.20:5062, enter the 12 digit IP address + *45062 (e.g.

1921680160*45062) after the voice prompt followed by the “#” key or wait for 4 seconds.

CALL HOLD Press the “flash” button to place a caller on hold. Press the “flash” button again to release call hold.

CALL WAITING If call waiting feature is enabled, call waiting tone (3 short beeps) indicates an incoming call. Toggle between incoming call and current call by pressing the “flash” button. First call is placed on hold. Press the “flash” button to toggle between two active calls.

CALL TRANSFER The HT496 supports both blind and attended transfer:

1. Blind Transfer: Press “flash” button (or hook flash on older models), dial *87, then dial the number to transfer call and press the “#” key (or wait 4 seconds) to complete transfer of active call.


Expected outcomes: a) A quick confirmation tone (call waiting tone) followed by a dial tone. This indicates the transfer is

successful. Hang up or place another call. b) A quick busy tone followed by a restored call (on supported platforms only). The busy tone

indicates the transfer failed. c) Continuous busy tone. The phone call has timed out. Note: continuous busy tone does not

indicate the transfer has been successful, nor does it indicate the transfer has failed. It often means there was a failure to receive second NOTIFY – check firmware for most recent release.

NOTE: “Enable Call Feature” must be set to “Yes” in web configuration page.

2. Attended Transfer:

Assuming that call party A and B are in conversation. A wants to Attend Transfer B to C: (1) A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a

dial tone (2) A then dial C’s number then # (or wait for 4 seconds). (3) If C answers the call, A and C are in conversation. Then A can hang up to complete

transfer. (4) If C does not answer the call, A can press “flash” back to talk to B.

NOTE: If Attended Transfer fails, and party A hangs up, the HandTone496 will ring party A to remind A that party B is still on the line. Party A can pick up the phone to resume conversation with party B.

3-WAY CONFERENCING HT496 supports Star Code Style or Bellcore Style 3-way Conference. Star Code Style 3-way Conference Assuming that call party A and B are in conversation. A (HT496) wants to bring C in a conference:

1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone. 2. A dials *23 then C’s number then # (or wait for 4 seconds). 3. If C answers the call, then A presses FLASH to bring B, C in the conference. 4. If C does not answer the call, A can press FLASH back to talk to B. 5. If A presses FLASH during conference, C will be dropped out.

Bellcore Style 3-way Conference Bellcore style 3-way conference is also supported. To use this method, the user must enable “Use Bell-style 3-way Conference” in FXS1 or FXS2 web configuration. Assuming that call party A and B are in conversation. A (HT496) wants to bring C in a conference:

1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone. 2. A dials C’s number then # (or wait for 4 seconds). 3. If C answers the call, then A presses FLASH to bring B and C into the conference. 4. If C does not answer the call, A can press FLASH back to talk to B. 5. If A presses FLASH during conference, C drops out.

It also has embedded HTML pages that allow users to configure the HT496 through a Web browser such as Microsoft’s IE and AOL’s Netscape. ACCESS THE WEB CONFIGURATION MENU The HT496 HTML (Web GUI) configuration menu is accessed either from the LAN or WAN port: FROM THE LAN PORT:

1. Directly connect a computer to the LAN port. 2. Open a command window on the computer 3. Type in “ipconfig /release”, the IP address etc. becomes 0. 4. Type in “ipconfig /renew”, the computer gets an IP address in 192.168.2.x segment by default 5. Open a web browser, type in the default gateway IP address. http://192.168.2.1. You will see the

login page of the device. FROM THE WAN PORT: The WAN port HTML configuration option is disabled by default from factory. To access the HTML configuration menu from the WAN port:

1. Enable the “WAN Port Web Access” option via IVR option 12.

2. Find the WAN IP address of the HT496using voice prompt menu option 02.

3. Access the HT496Web Configuration page by the following URI via WAN port: http://HandyTone-IP-Address (the HandyTone-IP-Address is the WAN IP address for the HT496).

NOTE: If using a web browser to enter the configuration page, strip the leading “0”s because the browser will parse in octet. (i.e. if the IP address is: 192.168.001.014, please type in: 192.168.1.14).

http://192.168.2.1/

END USER CONFIGURATION Once the HTTP request is sent from a Web browser, the user will see a log in screen. There are two default passwords for the login page:

User Level: Password: Web pages allowed: End User Level 123 Only Status and Basic Settings Administrator Level admin Browse all pages

Only an administrator can access the “ADVANCED SETTING” configuration page. FIGURE 3: SCREENSHOT OF CONFIGURATION LOG- IN PAGE

NOTE: If you cannot log into the configuration page by using default password, please check with the VoIP service provider. The service provider may have provisioned and configured the device for you. The Basic Configuration Page is the first web GUI the user will see.


TABLE 7: HT496 Basic Configuration Settings Definitions

End User Password Password to access the Web Configuration Menu. This field is case sensitive with a maximum length of 25 characters.

Web Port By default, HTTP uses port 80. This field is for customizable web port.

IP Address There are two modes to operate the HT496: DHCP mode: all the field values for the Static IP mode are not used (even though they are still saved in the Flash memory.) The HT496 acquires its IP address from the first DHCP server it discovers from the LAN it is connected. Using the PPPoE feature: set the PPPoE account settings. The HT496 will establish a PPPoE session if any of the PPPoE fields is set. Static IP mode: configure the IP address, Subnet Mask, Default Router IP address, DNS Server 1 (primary), DNS Server 2 (secondary) fields. These fields are set to zero by default.

DHCP hostname This option specifies the name of the client. This field is optional but may be required by some Internet Service Providers. Default is blank.

DHCP domain This option specifies the domain name that client should use when resolving hostnames via the Domain Name System. Default is blank.

DHCP vendor class ID Used by clients and servers to exchange vendor-specific information. Default is blank.

PPPoE account ID PPPoE username. Necessary if ISP requires you to use a PPPoE (Point to Point Protocol over Ethernet) connection.

PPPoE password PPPoE account password.

PPPoE Service Name This field is optional. If your ISP uses a service name for the PPPoE connection, enter the service name here. Default is blank.

Time Zone Controls how the date/time displays according to the specified time zone.


Daylight Savings Time Controls whether displayed time is daylight savings time or not. If set to “Yes” and the Optional Rule is empty, then the displayed time will be 1 hour ahead of normal time.

• The “Automatic Daylight Saving Time Rule” has the following syntax: o start-time;end-time;saving. Both start-time and end-time have the

same syntax: month,day,weekday,hour,minute o month: 1,2,3,..,12 (for Jan, Feb, .., Dec) o day: [+|-]1,2,3,..,31 o weekday: 1, 2, 3, .., 7 (for Mon, Tue, .., Sun), or 0 indicating daylight

savings rule is based on the day of the month. o hour: hour (0-23), o minute: minute (0-59)

• If “weekday” is 0, it means the date to start or end daylight savings is the given date. The “day” value must not be negative.

• If “weekday” is not zero and “day” is positive, then daylight saving starts on the first “day” of the week (1st Sunday, 3rd Tuesday etc).

• If “weekday” is not zero and “day” is negative, then daylight savings starts on the last “day” of the week (last Sunday, 3rd last Tuesday etc).

• Daylight savings is in minutes. If preceded by a (-), then subtract the number of minutes.

The default value for “Automatic Daylight Saving Time Rule” is US time: “04,01,7,02,00;10,-1,7,02,00;60”. Example: US/Canada, where daylight savings is applicable: 04,01,7,02,00;10,-1,7,02,00;60 Daylight savings starts from the first Sunday of April at 2AM and ends the last Sunday of October at 2AM.).

Device Mode Enables use of the device as a router or a bridge.

WAN side HTTP/Telnet Access

If set to “Yes”, user can access the configuration page through the WAN port, instead of through the “PC” port. Warning: this configuration is less secure than default option. Default is No.

Reply to ICMP on WAN port

If set to “Yes”, the HT496 will respond to the PING command from other computers, but it also is vulnerable to the DOS attack. Default is No.

Cloned WAN MAC Address:

Set a specific MAC address. Set in Hex format.

LAN Subnet Mask

Sets the LAN subnet mask. Default value is 255.255.255.0.

LAN DHCP Base IP:

Base IP for the LAN port which functions as a gateway for the subnet. Default value is 192.168.2.1.

DHCP IP Lease Time: Value is set in number of hours. Default value is 120hr (5 Days.) The amount of time IP address are assigned to LAN clients.

DMZ IP: Forward all WAN IP traffic to a specific IP address if no matching port is used by HT496or defined in port forwarding.

Port Forwarding: Forwards a matching (TCP/UDP) port to a specific LAN IP address with a specific (TCP/UDP) port.

In addition to the Basic Settings configuration page, end users also have access to the Device Status page.

TABLE 10: HT496 Individual Account Settings Definitions

SIP Server This field contains the URI string or the IP address (and port, if different from 5060) of the SIP proxy server. e.g., the following are some valid examples: sip.my-voip-provider.com, or sip:my-company-sip-server.com, or 192.168.1.200:5066

Outbound Proxy This field contains the URI string or the IP address (and port, if different from 5060) of the outbound proxy. If there is no outbound proxy, this field SHOULD be blank. If not blank, all outgoing requests are sent to this outbound proxy.

SIP User ID This field contains the user part of the SIP address for this phone. e.g., if the SIP address is sip:my_user_id@my_provider.com, then the SIP User ID is: my_user_id. Do NOT include the preceding “sip:” scheme or the host portion of the SIP address in this field.

Authenticate ID SIP service subscriber’s Authenticate ID. Auth ID can be identical to the SIP User ID.

Authenticate Password SIP service subscriber’s account password.

Name SIP service subscriber’s name for Caller ID display.

Use DNS SRV Default is No. If set to Yes the client will use DNS SRV for server lookup.

User ID is Phone Number If the HT496 has an assigned PSTN telephone number, this field should be set to “Yes”. Otherwise, set it to “No”. If “Yes” is set, a “user=phone” parameter will be attached to the “From” header in SIP request.

SIP Registration Controls whether the HT496 needs to send REGISTER messages to the proxy server. The default setting is Yes.

Unregister on Reboot Default is No. f set to Yes, the SIP user’s registration information will be cleared on reboot.

Register Expiration This parameter allows the user to specify the time frequency (in minutes) the HT496 refreshes its registration with the specified registrar. The default interval is 60 minutes (or 1 hour). The maximum interval is 65535 minutes (about 45 days).

Local SIP port Defines the local SIP port the HT496 will listen and transmit. The default value for FXS port 1 is 5060. The default value for FXS port 2 is 5062.

Local RTP port Defines the local RTP-RTCP port pair the HT496 will listen and transmit. It is the base RTP port for channel 0. When configured, channel 0 uses this port _value for RTP and the port_value+1 for its RTCP; channel 1 uses port_value+2 for RTP and port_value+3 for its RTCP. The default value for FXS port 1 is 5004. The default value for FXS port 2 is 5008.

Use Random Port This parameter forces the random generation of both the local SIP and RTP ports when set to Yes. This is usually necessary when multiple HT496 are behind the same NAT.

SIP Registration Failure Retry Wait Time

In case sip server fail from some reason, the HT496 will try to re-register not according to standard SIP timers, but according to preconfigured interval. Recommended to leave default value 20sec. Designed by special request of big service providers.

DTMF Payload Type This parameter sets the payload type for DTMF using RFC2833.

Send DTMF This parameter specifies the mechanism to transmit DTMF digit. There are 3 modes supported: 1) in audio which means DTMF is combined in audio signal (not very reliable with low-bit-rate codec), 2) via RTP (RFC2833), or 3) via SIP INFO. Multiple selections of DTMF method are supported.

Send Flash Event Default is No. If set to yes, flash will be sent as DTMF event.


Enable Call Features Default is Yes. Advanced call features and feature codes functions are supported

locally. Use Bell-style 3-way Conference

If this parameter is set to “Yes”, user will be able to make Bellcore style 3-way conference. *23 will be disabled.

Off-hook Auto-Dial This parameter automatically configures and dials User ID or extension number upon off-hook. Only the user part of a SIP address needs is entered here. The HT496 will automatically append the “@” and the host portion of the corresponding SIP address.

Proxy-Require SIP Extension to notify SIP server that the unit is behind the NAT/Firewall. Disable Call Waiting Default is No. User can use * code to use this feature per call basis. Disable Call Waiting Caller ID (CWCID)

Default is No. If set to YES, user will not be able to see CWCID information. If set to No, also requires support of this feature by analog phone connected to FXS port.

NAT Traversal (STUN) This parameter defines whether the HT496 NAT traversal mechanism is activated or not. If activated (by choosing “Yes”) and a STUN server is also specified, then the HT496 performs according to the STUN client specification. Under this mode, the embedded STUN client will detect if and what type of firewall/NAT is used. If the detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the HT496 will use its mapped public IP address and port in all of its SIP and SDP messages. If the NAT Traversal field is set to “Yes” with no specified STUN server, the HT496 will periodically (every 20 seconds or so) send a blank UDP packet (with no payload data) to the SIP server to keep the “hole” on the NAT open.

No Key Entry Timeout Default is 4 seconds. While dealing, the number will considered as completed if during this timeout no additional entry has been done.

Preferred Vocoder The HT496 supports up to 6 different Vocoder types including G.711 A-/U-law，G.723.1, G.726, G.729A/B, iLBC. Users can configure Vocoders in a preference list included with the same preference order in SDP message. The first Vocoder in this list is the appropriate option in “Choice 1”. The last Vocoder in this list is the appropriate option in “Choice 6”.

Voice Frames per TX Number of voice frames transmitted in a single packet. User should be aware of the requested packet time (used in SDP message). This parameter is associated with the first vocoder in the Vocoder Preference List or the actual payload type negotiated between the 2 conversation parties at run time. e.g. if the first vocoder is configured as G.723 and the “Voice Frames per TX” is set to 2, then the “ptime” value in the SDP message of an INVITE request will be 60ms because each G.723 voice frame contains 30ms of audio. If the configured voice frames per TX exceeds the maximum allowed value, the HT496 will use and save the maximum allowed value for the corresponding first vocoder choice. The maximum value for PCM is 10(x10ms) frames: • for G.726, it is 20 (x10ms) frames; . • for G.723, it is 32 (x30ms) frames; • for G.729/G.728, 64 (x10ms) and 64 (x2.5ms) frames respectively.

G723 Rate: Default is 6.3kbps rate. Defines the encoding rate for G723 vocoder.

iLBC frame size: Sets the iLBC frame size in 20ms or 30ms

iLBC payload type: Defines payload time for iLBC. Default value is 97. Valid range: 96 - 127.

Silence Suppression This controls the silence suppression/VAD feature of G.723. If set to “Yes”, a small quantity of VAD packets (instead of audio packets) will be sent during the a period of silence. If set to “No”, feature is disabled.

Fax Mode T.38 (Auto Detect) FoIP (fax over IP) by default, or Pass-Through (must use codec PCMU/PCMA)


Early Dial This parameter controls whether the early INVITE each time a key is pressed. If set to “Yes”, an INVITE is sent for each dialed number. If set to NO, INVITE is sent after the “(Re-)Dial” button is pressed or after 5 seconds have elapsed. The “Yes” option should be used ONLY if there is a SIP proxy configured and the proxy server supports 484 Incomplete Address response, otherwise the call is rejected. This feature is NOT designed to work with and should NOT be enabled for direct IP-to-IP calling.

Allow incoming SIP messages from SIP proxy only

Default is set to “No”. If set to “YES”, each incoming call will be checked first if it arrived from authorized proxy. Useful for security installation to prevent incoming calls from not authorized sources.

Allow outgoing call without Registration

Default is set to “No”. If set to “YES”, any outgoing call will be generated to the address specified in SIP Server field. Generation outgoing call in this case does not requires registration with any SIP Server.

Dial Plan Prefix Sets the prefix added to each dialed number

Use # as Dial Key If set to “Yes”, the “#” key as the “Send” (or “Dial”) key. If set to “No”, “#” key is part of the dial string.

Subscribe for MWI: Default is No. When set to “Yes” a SUBSCRIBE for Message Waiting Indication will be sent periodically.

Send Anonymous Blocks Caller ID display if set to “Yes”.

Lock keypad update If this parameter is set to “Yes”, the configuration update via keypad is disabled.

Refer-To Uses Target Contact

Used for Attended transfer Feature. The “Refer-To” header uses the transferred target’s “Contact” header information.

Special Feature Default is Standard. Choose this selection to meet special requirements from Soft Switch vendors.

Volume Amplification Adjusts handset volume. RX is for receiving volume, TX is for transmission volume. Default values are 0dB for both parameters. +6dB generates the highest volume and -6dB generates the lowest volume.

TABLE 11: HT496 AUDIBLE TONES SETTINGS PAGE DEFINITIONS

Audible Tones Using these settings, user can configure ring or tone frequencies according to their preference. By default they are set to North American frequencies. Frequencies should be configured with known values to avoid uncomfortable high pitch sounds. ON is the period of ringing (“On time” in ‘ms’) while OFF is the period of silence. To set a continuous ring, OFF should be zero. Otherwise, it will ring ON ms and a pause of OFF ms and then repeat the pattern.


SAVING THE CONFIGURATION CHANGES After making a change, click the “Update” button in the Configuration page. The HT496 will display the following screen to confirming changes. Reboot or power cycle the HT496 to enable the changes. FIGURE 4: SCREENSHOT OF SAVE CONFIGURATION PAGE

REBOOTING THE HT496 FROM REMOTE The administrator of the HT496 can remotely reboot the HT496 by clicking the “Reboot” button at the bottom of the configuration page. When finished, re-login to the HT496 after waiting about 30 seconds.

CONFIGURATION THROUGH A CENTRAL SERVER Grandstream HandyTone ATAs can be configured automatically from a central provisioning system. When HandyTone ATA boot up, it will send TFTP or HTTP request to download configuration file, “cfg000b82xxxxxx”, where “000b82xxxxxx” is the MAC address of the HandyTone ATA. The configuration files can be downloaded via TFTP or HTTP from the central server. A service provider or an enterprise with large deployment of HandyTone ATA can easily manage the configuration and service provisioning of individual devices remotely from a central server. Grandstream provides a licensed provisioning system called GAPSLITE that supports automated configuration of HandyTone ATA. GAPSLITE (Grandstream Automated Provisioning System) uses enhanced (NAT friendly) TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate with each individual HandyTone ATA for firmware upgrade, remote reboot, etc. Grandstream provide GAPS (Grandstream Automated Provisioning System) service to VoIP service providers. It could be either simple redirection or with certain special provisioning settings. Initially upon booting up, Grandstream devices by default point to Grandstream provisioning server GAPS, based on the unique MAC address of each device, GAPS provision the devices with redirection settings so that they will be redirected to customer’s TFTP or HTTP server for further provisioning. Grandstream also provide GAPSLITE software package which contains our NAT friendly TFTP server and a configuration tool to facilitate the task of generating device configuration files. The GAPSLITE configuration tool is now free to end users. The tool and configuration template are available for download from http://www.grandstream.com/configurationtool.html.

SOFTWARE UPGRADE Software upgrade can be done via either TFTP or HTTP. The corresponding configuration settings are in the ADVANCED SETTINGS configuration page.

FIRMWARE UPGRADE THROUGH TFTP/HTTP To upgrade via TFTP or HTTP, the “Firmware Upgrade and Provisioning upgrade via” field needs to be set to TFTP or HTTP, respectively. “Firmware Server Path” needs to be set to a valid URL of a TFTP or HTTP server, server name can be in either FQDN or IP address format. Here are examples of some valid URL. e.g. firmware.mycompany.com:6688/Grandstream/1.0.3.86 e.g. 168.75.215.190 NOTES:

• TFTP server in IP address format can be configured via IVR. Please refer to section CONFIGURATION GUIDE for instructions. If TFTP server is in FQDN format, it must be set via web configuration interface.

• End users recommended using our TFTP server. Its address can be found at http://grandstream.com/y-firmware.htm. Currently, the TFTP server, your HT496 can be upgraded from has an IP address 168.75.215.190. For companies, we recommend to maintain their own TFTP/ HTTP server for upgrade and provisioning procedures.

• Once a “Firmware Server Path” is set, user needs to update the settings and reboot the device. If the configured firmware server is found and a new code image is available, the HT ATA will attempt to retrieve the new image files by downloading them into the HT ATA’s SRAM. During this stage, the HT ATA’s LEDs will blink until the checking/downloading process is completed. Upon verification of checksum, the new code image will then be saved into the Flash. If TFTP/HTTP fails for any reason (e.g., TFTP/HTTP server is not responding, there are no code image files available for upgrade, or checksum test fails, etc), the HT ATA will stop the TFTP/HTTP process and simply boot using the existing code image in the flash.

• Firmware upgrade may take as long as 1 to 20 minutes over Internet, or around 20 seconds if performed on a LAN. We recommend that firmware upgrades be completed in a controlled LAN environment if possible. For users who do not have a local firmware upgrade server, Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware upgrade. Please check the Services section of Grandstream’s Web site to obtain our public TFTP server’s IP address.

• Alternatively, user can download a free TFTP or HTTP server and conduct local firmware upgrade. A free windows version TFTP server is available for download from http://support.solarwinds.net/updates/New-customerFree.cfm. The latest official release is available @ http://www.grandstream.com/y-firmware.html.

• User can also choose to download the free HTTP server from http://httpd.apache.org/ or use Microsoft IIS web server.

Directions to download a free TFTP Server:

1. Unzip the file and put all of them under the root directory of the TFTP server. 2. Put the PC running the TFTP server and the HT496 device in the same LAN segment. 3. Please go to File -> Configure -> Security to change the TFTP server's default setting from

"Receive Only" to "Transmit Only" for the firmware upgrade. 4. Start the TFTP server, in the phone’s web configuration page 5. Configure the Firmware Server Path with the IP address of the PC 6. Update the change and reboot the unit

CONFIGURATION FILE DOWNLOAD The HT496 can be configured via Web GUI as well as through the Configuration File through TFTP or HTTP. “Config Server Path” is the TFTP or HTTP server path for configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can be same or different from the “Firmware Server Path”. A configuration parameter is associated with each particular field in the web configuration page. A parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric numbers. i.e., P2 is associated with “Admin Password” in the ADVANCED SETTINGS page. For a detailed parameter list, please refer to the corresponding firmware release configuration template. When Grandstream Device boots up or reboots, it will issue request for configuration file named “cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e., “cfg000b820102ab”. The configuration file name should be in lower cases.

FIRMWARE AND CONFIGURATION FILE PREFIX AND POSTFIX Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix and Postfix. This makes it the possible to store ALL of the firmware with different version in one single directory. Similarly, Config File Prefix and Postfix allows device to download the configuration file with the matching Prefix and Postfix. Thus multiple configuration files for the same device can be stored in one directory. In addition, when the field “Check New Firmware only when F/W pre/suffix changes” is set to “Yes”, the device will only issue firmware upgrade request if there are changes in the firmware Prefix or Postfix.

MANAGING FIRMWARE AND CONFIGURATION FILE DOWNLOAD When “Automatic Upgrade” is set to “Yes”, Service Provider can use P193 (Auto Check Interval, in minutes, default and minimum is 60 minutes) to have the devices periodically check with either Firmware Server or Config Server, whenever they are defined. This allows the device periodically check if there are any new changes need to be taken on a scheduled time. By defining different intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration File download in minutes to reduce the Firmware or Provisioning Server load at any given time.


RESTORE FACTORY DEFAULT SETTING WARNING! Restoring the Factory Default Setting will DELETE all configuration information of the phone. Please BACKUP or PRINT out all the settings before you approach to following steps. Grandstream will not take any responsibility if you lose all the parameters of setting and cannot connect to your VoIP service provider.

RESET VIA IVR 1. Find the MAC address of the device. It is a 12 digits HEX number located on the bottom

of the unit. 2. Encode the MAC address. Please use the following mapping:

0-9: 0-9 A: 22 B: 222 C: 2222 D: 33 E: 333 F: 3333

For example, if the MAC address is 000b8200e395, it should be encoded as “0002228200333395”.

3. To perform factory reset: - Pick up the headset and dial “***” for voice prompt. - Enter “99” and get the voice prompt “Reset”. - Enter the encoded MAC address of the device. - Wait for 15 seconds. The device will reboot automatically and restore to factory

default setting. NOTE: 1. Factory Reset will be disabled if the “Lock keypad update” is set to “Yes”. 2. By default, the HT496 WAN side HTTP access is disabled. 3. After a factory reset, the device’s web configuration page accessible only from its LAN port.
